Wi-Controller-B - stand alone boiler controller

Wi-Stat III-SR wireless single relay thermostat is designed to retrofit any manual 2 wire Heat Only or Cool Only systems such as mercury switch, space heater thermostat or others. It is a battery powered intelligent energy conservation device that provides remote zone monitoring and control for commercial, industrial, and municipal HVAC environments. 

Designed to replace existing manual thermostats, the Wi-Stat III-SR provides Direct Digital Control features, such as remote wireless setpoint control and occupancy scheduling, continuous room temperature, branch line pressure and battery status monitoring, all of which were previously unavailable in HVAC systems.  The innovative design of Wi-Stat III-SR completely reshapes manual HVAC controls – it provides centralized controls previously unavailable with manual systems.
